Review on Enhance Your Engine Performance with Spectre SPE-1738 Chrome Oil Filler Plug by Jason Wright

This. I kept looking and found 3 that I liked because of the aluminum valve covers but not a lot of detail. I wanted one like this someone posted which they used on an old CJ jeep like mine but they had second thoughts and never did anything. I chose this one after reading a few less detailed reviews of a great fit. It is 1 1/4" above the flange but has a major diameter of 1,340". I couldn't insert it with one hand, I had to stand on the bumper to insert it. can turn it around My concern is that I can't pull it out all the way and I can pour oil into the PVC bushing hole. It's tight but I can move it up and down so I can still get the oil mist. It just can't be a good app for an old 258 Cijeep. I'll announce the date in a few months. TO UPDATE. A week later I was driving my CJ errands for about an hour and the last picture shows the oil leaking out. May work with other rocker covers but will not work with the Jeep CJ 6-row aluminum rocker cover. I didn't, I'll let you know next week.
